Sleeping Bags for Extreme Cold Expeditions

When you are mountaineering in the extreme cold or on a polar expedition the temperature will be very low so you will need the warmest cold weather sleeping bag possible.

Our sleeping bags that are suitable for polar or arctic expeditions come from Prime and Expedition ranges. These sleeping bags have minimum comfort temperatures from -18°C to -40°C. The best sleeping bag for you will depend upon how cold it is likely to be when you are mountaineering or exploring in polar conditions and how cold you get when you sleep.

All of our sleeping bags have excellent warmth to weight ratios and pack down to a small size.
